In 2024, some 2.3 million new cases of cancer worldwide were linked to infections — 12 per cent of all cases diagnosed that year — according to a study published in the journal The Lancet Oncology. Almost all of these cases are linked to five pathogens: the stomach bacterium Helicobacter pylori, the human papillomavirus (HPV), the hepatitis B and C viruses, and the Epstein-Barr virus. Low- and middle-income countries account for 77 per cent of all infection-related cancer cases.
A global review, which analysed 23 meta-analyses containing data on nearly three million children across 64 countries, identified associations between screen use and various aspects of children’s mental health and development. According to the authors, these findings may help to inform and refine guidelines and policies on screen use. The results are published in the journal JAMA Pediatrics.
A team led by the Silent Spring Institute (USA) drew up in 2024 a list of 921 chemicals that could increase the risk of developing breast cancer. They have now published an analysis of the presence of these compounds in everyday products in the United States. According to their findings, 485 are present in pesticides and as many as 462 in food, amongst other sources studied. Although the study does not allow for the estimation of risk or the establishment of causality, according to the authors, “transparency regarding how and where the population is exposed to these products will help to support public health research, exposure reduction and health protection regulations”. The study is published in Environmental Health Perspectives.
Following the publication of the results of the PISA 2025 report, the question arises as to how to interpret them and explain the possible causes of the decline in reading and maths results, both internationally and in Spain. We have sought the views of experts in education, sociology, inequality, educational technology and pedagogy.
A meta-analysis involving over a million participants has identified more than a thousand genetic variants associated with human personality. The study, published today in the journal Nature, examines the possible links between DNA variations and differences in personality. The results do not suggest that personality can be predicted from DNA, but rather that some variants may influence behavioural traits, whilst acknowledging that other environmental factors may have a greater impact. In their work, the authors focus on five traits: extraversion, agreeableness, conscientiousness, neuroticism and openness to experience.
A study published in the journal JAMA Network Open assessed the attitudes of Australian teenagers in the context of the implementation of minimum age restrictions on social media use in their country. The research team found that the majority of respondents expressed their intention to continue using social media after the regulations came into force, despite the fact that, in this sample, symptoms of anxiety and depression were associated with a history of social media use and with a younger age at the time of first use.
Every summer, algal blooms are common, from the Cantabrian Sea to the Mediterranean. Most play essential roles in aquatic ecosystems and have a high capacity to absorb CO₂. However, some can also cause problems, as is the case with the invasive alga Rugulopteryx okamurae, which has been spreading along the Spanish coastline for a decade.
Pupils who set up a social media account in early adolescence appear to perform less well in subsequent standardised tests, according to a study published today in Nature Human Behaviour and based on a sample of 5,227 Italian pupils. The study is observational, so it does not allow for a causal link to be established between social media use and academic performance. Furthermore, it was carried out using questionnaires in which students had to recall and report on their use of these services when they were younger.
An article published in Nature shows that the last Neanderthals in northwestern Europe exhibited greater genetic variability than previously thought, which, according to the authors, could call into question the idea that this was one of the causes of their extinction. The study included genetic data from 27 Neanderthals dating back about 52,500 years, found at ten sites in France and Belgium. The genome of a 45,000-year-old Neanderthal found in Belgium was also sequenced. According to the results, these Neanderthals lived in large, well-connected groups, as they showed no signs of inbreeding. Although they temporarily coexisted with early modern humans in that region, the study found no evidence of interbreeding with them.
A systematic review with a meta-analysis published in The Lancet Obstetrics, Gynecology, & Women’s Health concludes that there is insufficient evidence that most complementary treatments for in vitro fertilization (IVF) improve fertility in patients undergoing this procedure. Some of these techniques involve introducing platelet-rich plasma into the uterus or ovaries, administering a lipid infusion into the bloodstream, administering corticosteroids, or performing preimplantation genetic testing to detect aneuploidies—that is, abnormalities in chromosome number. According to the study, which included 85 clinical trials, there is only evidence—albeit of low quality—suggesting a possible benefit from three treatments: EmbryoGlue—a method of embryo transfer containing hyaluronic acid—endometrial scraping, and physiological intracytoplasmic sperm injection—a technique for selecting sperm.
